Dividing Fractions Looked at Math is Fun (in relation to dividing fractions.) There was a section on reciprocal of a fraction that talked about the simplicity of just turning a fraction upside down. And when you multiply a fraction by its reciprocal you get one. Best part was the ending quote "That is all. It's just too easy to talk about anymore." Really??? If only it were that simple! http://www.mathsisfun.com/reciprocal-fraction.html

Dividing Fractions
5th/6th grade
Although this is an ODE lesson tied to the old standards, it fits the CCSS for division of fractions. It includes a pre-test, lesson, and post-test.
